Phys.org / Mummified cheetahs found in Saudi caves shed light on lost populations
Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.
Phys.org / Complex life on planets orbiting the galaxy's most common stars may be unlikely
In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy.
Phys.org / Millions of working horses and donkeys face health risks from poor harnessing
These days, the mention of a carthorse or mule plowing a field would transport many people back in time to an era of horse-drawn carriages and pre-industrial agriculture.
Phys.org / Nationwide racial bias shapes media reporting on gun violence, study suggests
Mass shootings in white-majority neighborhoods received roughly twice the news coverage of mass shootings in neighborhoods where a majority of residents were people of color, while coverage of police-involved shootings was ...
Phys.org / Sharks are famous for fearsome teeth, but ocean acidification could make them weaker
Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth that regrow throughout their lives. But changes in the ocean's chemistry could put those weapons at risk.
Phys.org / Massive impact could be the cause of our lopsided moon
Our nearest neighbor, the moon, is still something of a mystery to us. For decades, scientists have wondered why it appears so lopsided, with dark volcanic plains on the near side (the side we see) and rugged, cratered mountains ...
Phys.org / X-ray four-wave mixing captures elusive electron interactions inside atoms and molecules
Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, opens a new way to see ...
Medical Xpress / Immune-targeting vaccine shows promise intercepting cancer in patients with Lynch Syndrome
The investigational cancer vaccine, NOUS-209, was found to safely stimulate the immune system to target precancerous and cancerous cells in individuals with Lynch Syndrome (LS), according to a study from researchers at The ...
Phys.org / How actin wavefronts rescue T cell receptors from endocytosis
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and ...
Medical Xpress / 1 in 5 people say losing their pet was worse than losing a person
For one in five people, losing a pet has been more distressing than losing a human loved one. New research has revealed that 21% of those who experienced both types of bereavement found their pet's death harder to bear.
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
Phys.org / Sri Lanka unveils a rare purple star sapphire claimed to be the biggest of its kind
A Purple Star Sapphire weighing 3,563 carats which is claimed to be the world's biggest of its kind was unveiled on Saturday in the Sri Lankan capital by the owners, who are ready to sell the precious stone which is estimated ...
